[Atrix 4G General] wintermute000:
OK I tried this procedure. seemed to work at first (got around 3% drain for nearly 2 hours of idling, but with everything turned on). Went to bed.

Then on the tram I foolishly then tried flashing kernels to test the latest faux123 OC/UV kernel. Instantly the bad drain issue returned, though difficult to say for sure as that was first time I put it through 'normal' usage pattern.

Enough is enough as I had swapped kernels a few times and upgraded my ROM, so I did a full data wipe, wipe cache, wipe dalvik cache, and flashed a full wipe version of Alien v4, leaving the kernel on stock. Did not resolve the poor battery life.

So: going to try this procedure again tonight lol but knowing this time its off a clean full wipe build.

When I say poor, I don't mean abysmal, I can make it through a workday, but only have 30% or less left, pretty poor IMO even with a fair bit of music listening.
[Atrix 4G General] Antzor:
Someone gave me credit for posting something like this but I originally got the idea from this thread, thanks xploited!
[Atrix 4G General] xploited:
You don't really need a custom rom. You only need root to wipe the battery stats (if you are on stock then you can wipe them through the Battery Calibration app obviously).

Besides that, skip the steps that relate to custom roms (like flashing battery fix CWM).

This procedure should recalibrate your battery to full capacity, and force Android OS to show the full capacity (by wiping old battery stats).

If something is still draining your battery, it must be one of the apps. You can find with the Watchdog app, or one of the battery monitoring apps.

Glad it helped. :cool:
[Atrix 4G General] wintermute000:
Not according to watchdog or betterbatterystats.....

anyhow I think issue is somewhat allieviated after I redid the whole thing after a full wipe, @ 88% after 2.5 hours which included 30 min of bluetooth mp3 so that's not too bad in my book. Thanks anyway I'll keep monitoring/looking.

Interestingly, after I did the full wipe and tried the 'pull battery at 100% and put it back in' trick, it showed at 100% and rebooted immediately instead of showing 5% and not going above 10% (which it DID do the first time I tried this procedure).
[Atrix 4G General] :
So I followed this post and I have had tremendous battery life. I would post a picture but I need 10 posts so I will be back when I have said posts and edit this to include it :)

Thank you though, for your testing and clear and concise instruction on fixing this problem people seem to be having
[Atrix 4G General] xploited:
Did the BatteryCalibration app show 4200MV after the procedure? If so, then you have successfully returned to full battery capacity.

The pull out trick (LOL) shows different numbers for different people I suppose, I've had three different % readings on three phones doing the exact same thing.

Awesome, glad it helped. Some people complain that the procedure didn't help them, so it's nice to see all these people that did resolve their problem with this procedure. :cool:

Hi i did all the steps of ur post. and i managed to get 4209mV at 100% battery

but i am having a problem, i am rit Now my battery is at 39% and is 3730mV. soon battery will be 0% and i am sure ill be having 3300+mV ramaning.

Any suggestions.

i am using Alien ROM
[Atrix 4G General] xploited:
MV measurement doesn't show the battery capacity. It shows "how strong the electrical current from the battery to the phone is" (I am sure my wording is wrong here) LOL :cool: .

So, it's ok that your battery doesn't show 0 MV when you discharge it. :p ;)
[Atrix 4G General] xateeq:
Dont tell me that, i did all of those steps for nothing, i always get 4209-7 at 100% :(

any suggestions how to improve battery ?

I am also using setcpu and it is good but not comparable to froyo, i usually get around 2 days of battery with medium usage. now in GB its only 1 day max :(

and what is the actual purpose of watchdog in battery saving ? all it does is notify me.
[Atrix 4G General] xploited:
Freeze all MotoBlur processes with Titanium Backup (there's a thread in the General section about which processes are safe to freeze).

I usually get two days of usage on GB easily. I see you are already using a custom kernel with profiles.

Watchdog helps you find apps that consistently use too much CPU. If you get constant notifications about some app - uninstall it.

I am back with update,

till tomorrow nothing worked and i didn't freeze any process (nor planning to) but i am having gr8 battery life now and all i did was downloaded the

[ GINGERBREAD Kernel 2.6.32.9 ]

[ Overclock Kernel, Max @ 1.1 GHz ]

The CWM File ==> Unified GB Kernel Version 0.1.6 <==

http://xdaforums.com/showthread.php?t=1156040

Flashed it (instructions are on the link)

and setcpu profile (screen off profile max 416 min 216)

and i am having amazing battery life. last night went to sleep at 89% and wake-up with 85% (8 hrs or sleep)

Every thing is amazing smooth and new kernel is over clocked (i am not using over clocking)

Try it, it should provide significant results.

P.S: i am dam sure that ill get more battery life then froyo (i am using Alien #4 ROM)
[Atrix 4G General] xploited:
Well, I don't have a need for custom kernel, as I am getting great battery life without it. But yes, custom kernel with correctly configured profiles is a known battery booster (doesn't work for everyone though).

I originally intended to updated this guide with post#2 about standard practices to extending battery life, but I forgot to reserve post 2 for this, oh well :o.

My battery is already showing 4200 so should I still go thru with this entire process...?? Tho my battery only charges till like 96 or 97% and says its full...
[Atrix 4G General] DrunkFuX666:
Hmmm... what's strange I just noticed... at 96% it told me full charge with 4200... now after a few mins says 98% with 4198...
[Atrix 4G General] brd912:
I know this will fix my battery problem,and I'm gonna do it up tomorrow. Quick question though. I got a brand new battery a few days ago,I popped it in and charged overnight while I slept. Woke up and unplugged and the phone literally sat untouched, for 3 hours. When I picked it up,it was at 97%,so I was like cool. Throughout the day with heavy usage,after 15 hours on battery,it was at 30%,I was speechless. So I let it die and recharged to 100%,and when I unplugged it started draining like it did before,very,very quickly. Anyone know why it would do that?
[Atrix 4G General] wintermute000:
yah found the gtalk sign out setting last night. But didn't seem to matter.

so far today around 7 hours off the charger and gtalk_async_conn is 30 minutes worth of wakelocks... no I'm not signed in!!!

my battery life is now a bit better mind you (end the day around 50% with a fair chunk at least 2 hours of mp3 listening) but its still not as good as what some people are claiming. I really want to know why gtalk is wakelock even though its defo not running (when I click on the talk icon, it signs me in, so I know it wasn't signed in previously).

As for 98% issue, yeah I got same issue too
[Atrix 4G General] xploited:
The battery meter on the Android phones isn't 100% accurate, see this:

http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/

If you let it sit plugged into the charger it will eventually get to 100%.

Which problems are you having with the battery though?
[Atrix 4G General] xploited:
Either you need to do recalibration, or one of the apps is draining the battery.
[Atrix 4G General] xploited:
Hmmm... haven't heard about this issue before. I will look at mine if it does the same thing.

Is there anything else that strangely uses the CPU? Did you do recalibration?
[Atrix 4G General] DrunkFuX666:
Well I feel my battery drains wayyyy too fast... like I need to charge it 3 tines a day... twice atleast... I do use it alot as well but I used my previous SGS the same amount... with a smaller battery... yet never ever had to charge more than twice... once would do and max twice...

I do know the alarm manager causes the wakelock for a very large percentage hence my phone is usually always awake even when not in use... not been able to find a way around that yet... otherwise the apps that would tend to cause the wakelock have been able to control them...

Its just I see ppl reporting 2-3 days of use and im like wtf am I doing wrong... I only want 24hours of use and ill be totally happy...!!

I would try disabling alarm manager for one day and see how much it helps.
[Atrix 4G General] DrunkFuX666:
But isn't that some important system file... will it not screw with something else if I do it...??

Also you didn't mention if I should go thru with the whole calibration process or not since im already at 4200 at a full charge...

Sent from my Motorola Atrix
[Atrix 4G General] xploited:
I meant just turn off the alarms for one day (like a weekend). :)

4200 should be full capacity, so I would do recalibration only as last resort. Try freezing bloatware and monitoring your apps with Watchdog. :)
[Atrix 4G General] wintermute000:
Nope, and yes all calibrated etc. this appears to be the last hurdle.

Also re: alarmmanager, I've googled it extensively, its actually a 'catchall' service that lets other apps hook in and set off updates sync etc. its NOT JUST FOR ALARMS. Straight from the horses mouth.

http://developer.android.com/reference/android/app/AlarmManager.html

I suppose there would be a way to check the log to see what apps are using that service but haven't gotten that far in (on mine, stupid gtalk takes up more wakelocks than alarmmanager lol)

Try this radio...

For anyone who still have battery drainage problems, you can try flashing radio 1.77.30p. Read this post started by J-Roc:

http://xdaforums.com/showthread.php?t=1226178

I basically had bad battery life ever since i flashed 2.3.4 and tried many roms and kernels.. even this calibration method didn't work for me. This radio did the trick. I went from 10% drainage/hour to less then 1% (idle of course)
[Atrix 4G General] wintermute000:
yep sync always on. I didn't buy dual core 1930mah battery for nothing lol

if you mean though is it always transmitting then no, it does idle most of the time according to the icon anyway!!!

i have watch dog installed and android system is frequently going over 20% usage with my phone just sitting in my pocket, is there a way I can fix this?
[Atrix 4G General] efishta:
Is anyone else's WiFi always on when set to "Never when plugged in"?

I unplugged it last evening, didn't plug it back in till this afternoon and WiFi has been on for 15 hours. I just think that's weird, considering I was asleep and didn't use the phone for 6-7 hours.

On the Nexus One, it did disable WiFi after a while when screen was off because I remember it would reconnect after I turned it on (from standby). On the Atrix it's always connected. I do have push notifications for two email accounts, so I'm guessing that's what's causing it.

Any similar experiences?
[Atrix 4G General] Noob777:
Done

Ok. I've done everything except install the fix because i got an error saying that it was "bad". i went ahead anyway and skipped to erasing the battery stats. then i rebooted and saw that i had 4200 mV. set watchdog settings and left it on. now im just waiting for results

EDIT: so after about 4.5 hours, the battery went from 100% to 98%.

According to watchdog, there's something called IRQ and softIRQ running. im not worried, they take <1% of my battery.

Anyway my battery seems to be running great now. After checking it again on battery monitor widget it jumped from 98 to 100%. What's wrong now?
[Atrix 4G General] xploited:
Just the number 20% tells us nothing. Please, post statistics (battery life, % used by android system, etc).
[Atrix 4G General] xploited:
Sync always + data always on is definitely what's draining some of the battery.

If you are getting at least a day of battery life with this setup, then I am afraid you can't do much better than this without disabling things. :cool:
[Atrix 4G General] divante:
Done everything listed here and got some battery improvement, but my phone is still draining about 10% battery per hour if I only let data + sync on. If I use it and start hearing music, well, then it goes down more than twice faster.

My settings are the same as they were before I changed to 2.3.4 (just email and twitter syncing, everything else is off), and with 2.2 my phone could go thru the day with 24h of music on and still have about 15% by the end of the day, but since 2.3.4, either I give up on listening to music our bring along my wall charger (USB charging doesn't beat the battery draining). Any ideas of what I could try to do other than let my phone charging 24/7? ):

Already went back to stock kernel and radio, my batt with 100% is at 4196mV, and now I'm curently using the latest Aura rom. Tried Alien and piCrust, but none improvement on battery life =/

Btw, nice tips you got here! Thanks for posting them (;
[Atrix 4G General] ranova:
yep, I get about 10% drain on 3g no matter what I do. so it lasts around 9-10 hours IF i leave it idle the entire time; pretty pathetic.

On wifi, I get about double that - 5% an hour so it lasts around 20 hours if I leave it on idle. I remember on my old Captivate, on wifi, it would last 36-48 hours easily

Ive tried undervolting, setting up a sleep profile in setcpu, freezing apps, recalibrating the battery, etc.
[Atrix 4G General] tight686:
I as well suffer from odd battery life. I live in Minneapolis surrounded by HSPA and I just made a 5 minute call from fully charged and browsed XDA to read this (on WiFi) and I'm at 96%.

Not even my Infuse was that bad.
[Atrix 4G General] xploited:
Guys, 10% drain per hour is definitely WAAAAAY too much.

Can you do a test for one or two days and disable Data connection to see how much it affects the battery? I seriously feel that's what is draining your batteries.

If the draining issue persists after you disable data, then one of the apps is at fault, no doubt about it. You can find it with Watchdog or advanced battery stats app posted here which measures wakelocks.
[Atrix 4G General] tight686:
I use Green Power premium to switch my data on and off. 1 on 10 off. Screen off my phone loses 10% every 3-4hrs. Screen on is a different story entirely.

My methode to limit drain

Go market and download "Android Assistant"

Go tool and stop flip landscap detector what is very hard for atrix battery

Go to startup tool and bloc start of all unwanted app / system app

After, run setcpu and underclock at screen off

Install other rules like underclock under percent bat limite (50% 25%)

JD is a good way but for wifi limitation

Better is 3g watchdog pro to trace app drain by air cunsumption

Air push detector can be use to see hack app

How should I charge my phone every night after doing the procedure in OP?
[Atrix 4G General] xploited:
The procedure needs to be completed only once. After you have completed it, use and charge your phones as you would normally.
[Atrix 4G General] rush_ad:
The battery calibration app shows that my phone has 40% and 3742 mV charge remaining.

The OP (in OP pics) shows that phone had 72% and 3922 mV charge remaining.

I am experiencing some battery problems from last two days, however before that it used to work fine. My phone is totally stock, never rooted and never unlocked the bootloader. However it is SIM unlocked by a code provided by AT&T.

You guys feel that my phone needs calibration?

I am trying to avoid messing with the phone to keep the warranty. I read everywhere that unlocking the boot loader is permanent and cannot be reversed.
[Atrix 4G General] spendrup:
Do you guys think it's always necessary to install a fix? I was at 70% today at 15:30, did a reboot and the battery said 100%, which couldn't be true of course (1st time it happens btw, OrangeFR 2.3.4 with Edgan's Kernel)

"Simple Battery Widget" said 3900mV and 100% , but instead of disconnecting the atrix and deleting batstats I kept it connected to USB. The voltage went up to 4200mV (my previous standard 100% voltage) within the next hours:

4041mV 16:17

4061mV 16:19

4072mV 16:24

4142mV 16:52

4189mV 17:09

4200mV 17:38

Maybe instead of fixing the battery indicator after every reboot someone could make a widget indicating the voltage instead of the systems battery status...
[Atrix 4G General] rush_ad:
I have very much the same problem as you. But I am keeping it plugged in but my voltage doesn't increase like it did for you. The Simple Battery Widget shows that it is 100% charged with 3856 mV.
[Atrix 4G General] Vangelis13:
My battery has never hit more than 4196, is that a sign of it being damaged or something?
[Atrix 4G General] spendrup:
I have to correct the values, 4200mV is with cable plugged in, mine drops to ~4150mV when plugged off...
[Atrix 4G General] Vangelis13:
No, mine drops as well to something similar when unplugged. But still, it never reaches 4200. Oh well, suppose all batteries are different?

P.S. Right now it's charging on the wall and it's at 94% - 4191mV. This value will fluctuate a bit until I hit 100 but it will not reach 4200..
[Atrix 4G General] rush_ad:
Where does this 4200 mV number come from?

The Battery Calibration app is generic for all phone but all phones have different size batteries with Atrix having the largest 1930 mAh battery of all phones!!!

Then what's so magic about 4200 mV?
[Atrix 4G General] spendrup:
Nothing special, just my highest voltage when charging via USB. Maybe yours would be 4218...:)
[Atrix 4G General] dragoncius:
My phone has been charging for over 3 hours and it doesnt reach 100% charge...even though Battery Calibrator says it is at 4200....any thoughts?

[Atrix 4G General] xploited:
If your phones shows 4200mv while at 100% then you are fine.

What kind of battery problems are you having?

If you reboot, the battery indicator usually doesn't show the correct percentage for the first 10-30 minutes.

Try doing a couple of charge-discharge cycles.

If your battery returns to normal and you have 4200mv after charging to a 100%, then you are fine.

Otherwise - try doing the calibration.

Your battery might have worn off some of it's capacity. For how long do you own this phone? If you flash roms frequently, always try doing recalibration and it might return to 4200mv.

4200 - is voltage "strength" when battery is at full capacity. This is stated even by official BatteryCalibration app developer. This number doesn't relate to battery capacity.

If it shows 4200mv, then you have nothing to worry about.

The battery meter isn't 100% correct,... see this article -

Judging by the name, it's something to do with the graphics driver. So, I obviously wouldn't freeze it.

[Atrix 4G General] :
I'm on my third Atrix in 30 days (AT&T was dumb enough to replace the other two :D) and all of them charged up to 4200/100%. I always reset the stats at this point after installing a new rom and never had any weird problems since.
